Many Early Sprinters (2004 to 2007) suffer from blown intake and turbo air tubes and broken resonators.  Typical symptoms of a blown tube or broken resonator are a loud hissing noise and lack of engine performance when accelerating, often accompanied by the orange check engine light on. Precision Auto has solved some of these problems by sourcing the Riordan aluminum resonator that will not crack and break, like the factory one does. This update gives you the added reliability you need from your Sprinter!
